Long Covid patients are being haunted by "unbearable" odours like fish and burning in place of normal smells, researchers say, as more unusual symptoms of the virus emerge.
ENT (ear, nose and throat) surgeon Professor Nirmal Kumar said this "very strange and very unique" long-term symptom known as parosmia seems to be affecting young people and healthcare workers in particular.
The surgeon, who is also the president of ENT UK, was among the first medics to identify anosmia, loss of smell, as a coronavirus indicator in March, and urged Public Health England to add it to the symptom list months before it became official guidance.
